Adjustable Chiral Ophthalmic Lens

摘要

The present invention relates to an adjustable ophthalmic lens comprising at least one optical element comprising a combination of at least two optical surfaces wherein both optical surfaces are chiral optical surfaces adapted to provide chiral modulation of the light beam, the combination of the chiral optical surfaces is adapted to provide at least one adjustable focus and the combination of the chiral optical surfaces is adapted such that the focal distance of the adjustable foci depends on the mutual position of the chiral optical surfaces. These chiral optical surfaces result in a chiral modulation of the light beam. Combinations of chiral optical surfaces are applied to obtain adjustable optical powers in single-focus ophthalmic lenses and multiple-focus ophthalmic lenses.
